NOTAM also have quality problems

… runway shortenings when the NOTAM simply gives a new TORA and does not really say WHERE the runway have been shorter (in what end)

… complex restricted area boundaries that take hours to put on a map!

… obstacles with imprecise positions

… irrelevant information

… typing errors

… very long and complex to read!!!

10% of the NOTAM have errors

according to a study done by the EAD

on randomly selected messages!

Pilot’s Perspective

• “Last line of defense” for safety

• Typically have less time to review NOTAMs than other customers

• NOTAM data not filtered or prioritized

• Digitize NOTAM data

• Instead of<text>TAXIWAYS OUTER 7 AND E6 CLSD</text>

• Use explicit feature properties• For example…

<taxiway> <name>OUTER 7</name> <status>CLOSED</status></taxiway><taxiway> <name>E6</name> <status>CLOSED</status></taxiway>

What is a “digital NOTAM”

Benefits – improved data quality

Digital data: • clearer / more precise than free text• enables validation

• automatic by the system• visually by the operator

Benefits – improved PIB

Positive impact on safety

Benefits – airspace activity maps for VFR

Digital NOTAM Event Specification - Purpose

Digital NOTAM Event Specification

• Incremental approach• Version 1.0

• Published June 2011• Reviewed / tested by industry in prototypes

• Version 1.1 – in preparation• Modifications based on feed-back from industry• Include “missing” events (surface contamination, TWY

closure)• Include additional events• Working version available on line (see link in the document)

Version 1.1 (tentative)

• Increment 1 scenarios • Increment 2 scenarios

• Published special activity area – activation • Displaced threshold

• Published ATS airspace - activation or deactivation • Declared distances changes

• Ad-hoc special activity area – creation • Runway portion closure

• Ad-hoc ATS airspace – creation • Airport Usage limitation

• Route portion closure • Runway usage limitation

• Route portion opening • Taxiway usage limitation

• Aerodrome closure • Approach lights unserviceable

• Runway closure • Approach lights downgraded

• Navaid unserviceable • Runway lights unserviceable

• New obstacle • Obstacle lights unserviceable

• Taxiway closure • Visual Approach slope indicator unserviceable

• Surface contamination (SNOWTAM) • Taxiway lights unserviceable

• Other Event (any other situation that does not have a dedicated scenario)

First implementations

• SESAR P.13.2.2 • Thales prototype – Airport closure• Frequentis prototype – New obstacle

• Other implementations by industry• IDS (cooperation with ENAV) prototype – All increment 1• Comsoft prototype – Runway closure, etc.

• Eurocontrol• DiNO prototype – airspace warnings / reservations

• FAA• Digital NOTAM submission – operational system• System deployed at more than 100 airports already

FAA Digital NOTAM implementation

Trial – Application architecture

AIXM 5.1 data

• Users can access the data :• through REST

interface • through WFS

Icon Meaning

No contamination information on the airport

Contamination information exists– breaking action GOOD

Contamination information exists– breaking action POOR or UNRELIABLE

All other situations, including airport/heliport closed

The latest SNOWTAM received could not be parsed due to syntax error. Available via the Manage Rejected SNOWTAM menu
